Fe–Pt films prepared from plating baths containing glycine as a complexing agent

AIP Advances
We have reported Fe–Pt films with hard magnetic properties electroplated from plating baths using citric acid as a complexing agent. The present study focuses on glycine as a new complexing agent instead of citric acid.

Exploration of the Reduction Diffusion Temperature for Different Phases of Samarium–Cobalt Magnetic Particles

Molecules
We report a method for synthesizing different phases of samarium–cobalt particles through microwave-assisted combustion combined with high-temperature reduction and diffusion, and identify the optimal temperature for forming the 1:5 phase using this ...

Recent advances in SmFe12-based permanent magnets

Science and Technology of Advanced Materials, 2021
To realize a sustainable society, ‘green technology’ with low (or even zero) CO2 emissions is required. A key material in such technology is a permanent magnet because it is utilized for electric-power conversion in several applications including ...

Coercivity and Exchange Bias in Ti-Doped Maghemite Nanoparticles

Magnetochemistry, 2022
Ti-doped maghemite nanoparticles of average crystallite size 12.9 nm were synthesized using the sol–gel method. The XRD profile mainly showed the presence of maghemite phase with very small phases of TiO2 (rutile and anatase).

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Global weak solutions to degenerate coupled transport processes in partially saturated deformable elastic-inelastic porous media

Electronic Journal of Differential Equations, 2020
In this work we prove the existence of global weak solutions to a degenerate and strongly coupled parabolic system arising from the transport processes through partially saturated deformable porous materials.

Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

Advanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.
